Dasiphora plant named ‘Hachliss’

ABSTRACT

A new cultivar of  Dasiphora  plant, ‘Hachliss’, that is characterized by its compact, bushy, and dwarf plant habit, its very floriferous blooming habit; blooming from July to September in Germany, it flowers that are deep red-pink in color, and its resistance to powdery mildew and red spider mites.

Botanical classification: Dasiphora fruticosa subsp. fruticosa.

Variety denomination: ‘Hachliss’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Dasiphora fruticosa subsp. fruiticosa. The new cultivar will be referred to hereafter by its cultivar name, ‘Hachliss’. ‘Hachliss’ is a new cultivar of shrubby cinquefoil grown for use as a landscape shrub.

The new cultivar is the result of a controlled breeding program conducted by the Inventor in Barmstedt, Germany. The intent of the breeding program is to develop new cultivars of Dasiphora with brightly colored flowers. The new cultivar arose from a cross made by the Inventor in Barmstedt, Germany in summer of 2003 between the cultivars ‘Rosiflor’ (not patented) as the female parent and ‘Red Ace’ (not patented) as the male parent. The Inventor selected ‘Hachliss’ as a single unique plant amongst the seedlings that resulted from the above cross in July of 2006.

Asexual propagation of the new cultivar was first accomplished by the Inventor by softwood stem cuttings in Barmstedt, Germany in 2012. Asexual propagation by softwood stem cuttings has determined that the characteristics of the new cultivar are stable and are reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and represent the characteristics of the new cultivar. These attributes in combination distinguish ‘Hachliss’ as a unique cultivar of Dasiphora.

-   -   1. ‘Hachliss’ exhibits a compact, bushy, and dwarf plant habit.     -   2. ‘Hachliss’ exhibits a very floriferous blooming habit;         blooming from July to September in Germany.     -   3. ‘Hachliss’ exhibits flowers that are deep red-pink in color.     -   4. ‘Hachliss’ has been observed to be resistant to powdery         mildew (Podosphaera aphanis) and red spider mites (Tetranychus         urticae) on trials to date.

The female parent of ‘Hachliss’, ‘Rosiflor’, differs from ‘Hachliss’ in having smaller flowers that are bluish pink in color and in having a taller more uneven plant habit. The male parent of ‘Hachliss’, ‘Red Ace’, differs from ‘Hachliss’ in having a more vigorous growth rate and in having red colored flowers that fade quickly after opening. ‘Hachliss’ can be most closely compared to the Dasiphora cultivars ‘Pretty Polly’ (not patented) and ‘Pink Beauty’ (U.S. Plant Pat. No. 9,874). ‘Pretty Polly’ differs from ‘Hachliss’ in having flowers that are bluish pink in color, in having a prostrate plant habit, and in having a less floriferous blooming habit. ‘Pink Beauty’ differs from ‘Hachliss’ in having semi-double salmon pink colored flowers, in having an upright plant habit, and in having a less floriferous blooming habit.
